When people want to buy tarps, they head out to tarp retailers. There are two kinds of tarp retailers and they sell very different kinds of tarps. One kind of tarp retailer sells camping tarps. Camping tarps tend to be small and are used by campers to protect campers from the elements. Camping tarps are often made of plastic or synthetic waterproof fibers. Camping tarps can often be bought at camping stores or tent stores. The second kind of tarp retailer sells the large tarps that are used to cover sensitive pieces of ground so as to protect them against the elements. These larger tarps are usually made of plastic or made of a breathable waterproof material. Many retailers that sell this kind of tarp can custom make tarps according to the dimensions of the piece of land that needs to be covered. Tarps are commonly used to cover baseball diamonds and golf greens during the winter.
